As a society, we are increasingly aware of the environmental impact of human activity and the dire need to develop cleaner technologies and to use our resources more efficiently. Baines is a world-renowned researcher in main group chemistry with a research focus on the synthesis and chemistry of the unsaturated derivatives of heavy Group 14 elements. The long term vision for her research program is to use her extensive knowledge and understanding of the chemistry of unsaturated Group 14 compounds to provide innovative solutions which address these important societal challenges. The proposed research can be divided into three themes. Theme 1: She proposes to synthesize ligand-stabilized silicon dications and ligand-stabilized binary germanium and tin chalcogenides and to examine the conversion of these simple complexes to nanomaterials. Theme 2: Two methods for the elaboration of ammonia to amines, reagents used in many areas of chemistry, will be examined. She will explore the insertion of alkenes into the NH bond of ammonia utilizing amido-substituted germanium or tin(II) compounds as catalysts. She will also investigate the reaction of doubly-bonded compounds of the heavier Group 14 elements with ammonia as a second method for the synthesis of functionalized amines. Theme 3: She will develop alternative methods for the synthesis of technologically important germanium and tin compounds which avoid the use of highly corrosive and toxic chlorine-based reagents. The vision is to develop industrially-relevant protocols for the processing and recycling of germanium and tin which are efficient and environmentally-friendly to ensure that these two important elements will be available for future generations. Hexacoordinate complexes of germanium and tin will be utilized as key intermediates and the synthesis and reactivity of several complexes of this type will be explored. The Baines research program will provide excellent training opportunities for students and the results will contribute new knowledge which can be used to address two important chemical challenges: how to derivatize ammonia and how to cleanly produce technologically important materials. Baines was awarded the Humboldt Research Award from the Alexander von Humboldt Foundation in Germany and the Montreal Medal from the Chemical Institute of Canada, both in 2016. She was a DAAD Scholar (Research Stay for University Academics and Scientists from the German Academic Exchange Service) at the University of Oldenburg in 2015. In the last 6 years, she has published 33 journal articles, 2 data reports and given 36 invited presentations including 4 plenaries. She has supervised 30 HQP, including several national scholarship winners. Her HQP have given 31 conference presentations across the globe. Over 90% of the students she has supervised are contributing directly to the Canadian economy as academics and professional chemists.

作为一个社会，我们越来越意识到人类活动对环境的影响，以及迫切需要开发更清洁的技术和更有效地利用我们的资源。贝恩斯是世界著名的主族化学研究者，主要研究14族重元素的不饱和衍生物的合成和化学。她的研究计划的长期愿景是利用她对不饱和第14族化合物化学的广泛知识和理解，提供创新的解决方案，以应对这些重要的社会挑战。拟议的研究可分为三个主题。主题一：她建议合成配位体稳定的硅二价阳离子和配位体稳定的二元锗和锡硫族化物，并研究这些简单的复合物向纳米材料的转化。主题2：两种方法的阐述氨胺，试剂中使用的许多化学领域，将进行审查。她将探索利用氨基取代的锗或锡（II）化合物作为催化剂将烯烃插入氨的NH键中。她还将研究较重的第14族元素的双键化合物与氨的反应，作为合成官能化胺的第二种方法。主题三：她将开发技术上重要的锗和锡化合物的合成替代方法，避免使用高腐蚀性和有毒的氯基试剂。我们的愿景是为锗和锡的加工和回收制定工业相关的协议，这些协议是高效和环保的，以确保这两种重要元素将为后代所用。锗和锡的六配位络合物将被用作关键中间体，并将探索这种类型的几种络合物的合成和反应性。 贝恩斯研究计划将为学生提供极好的培训机会，其结果将有助于新的知识，可用于解决两个重要的化学挑战：如何衍生氨和如何清洁生产技术上重要的材料。 贝恩斯被授予洪堡研究奖从亚历山大冯洪堡基金会在德国和蒙特利尔奖章从加拿大化学研究所，都在2016年。2015年，她是奥尔登堡大学的DAAD学者（德国学术交流服务中心的大学学者和科学家研究）。在过去的6年里，她发表了33篇期刊文章，2份数据报告，并提供了36次邀请演讲，包括4次全体会议。她指导了30名HQP，其中包括几名国家奖学金获得者。她的HQP已经在地球仪的31个会议上发表了演讲。超过90%的学生，她已经监督直接贡献给加拿大经济作为学者和专业化学家。
